THOMAS WRIGHT, DECEASED, LATE OF JERSEY CITY, NEW JERSEY, BY THOMAS EUGENE WRIGHT, OE JERSEY CITY, NEW JERSEY, AND JOHN F. WRIGHT, OF

CLINTON, NEW? JERSEY, EXECUTOES.

DUMPI'NG WAGON AND CART Specification of Letters Patent. 2 Patented N 18 1919 Appilcation filed December 7, 1917. Serial No. 206,030.

To all whom 2'25 may concern Be it known that THOMAS \Vnieirr, de ceased, late a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, invented certain new and useful Improvements in Dumping Wagons and Carts,- of which the following is a specification.

The object of the invention is to provide means for elevating and controlling the position of a wagon body with reference to the supporting truck whereby a maximum elevation may be secured when it is desired to deliver material, such as coal, to chute for conveying the same for a considerable dis tance, and whereby a modified or increased inclination of the body may be secured when the vehicle is used in the transportation of materials which flow or discharge less readily from the container, or whereof the angle of rest is less than that of coal and similar materials.

Further objects and advantages of the in vention will appear in the course of the following description, it being understood that changes in form, proportion and details of construction be resorted to within the scope of the appended claims and without departing from the spirit of the invention.

In the drawings illustrating one embodiment of the invention- Figure 1 is a side elevation partly broken away of a vehicle equipped with the body elevating and positioning mechanism.

Fig. 2 is a similar view showing the body in its elevated position, the full lines indicating the maximum elevation and the dotted lines the maximum inclination.

Fig. 3 is an enlarged detail with parts of the elevating mechanism in position to give the body its maximum elevation.

' Fig. 4 is a vertical transverse section.

Fig. 5 is a detail. view of a support extension or shackle.

The body elevating device of the present invention is shown in connection with a motor operated truck 10 of any suitable type and construction with which are connected the fore and aft supporting members 11 and 12 having connection at their upper ends with the body 13 which is adapted to be elevated and inclined require to secure the dumping action. The aft or rear supporting member may consist as illustrated of bars pivotally connected terminally to the truck and body as shown respectively at 1 1 and '15. The forward supporting member preferably consists of bars of which the lower ends are connected with extension elements or shackles 16 pivotally mounted as at 17 upon the truck and normally lying in seats 18 where they are held by suitable locking means such as cotter pins 19.

The thrust member 20 by which the body is elevated preferably consists of bars connected as hereinbefore described with the body and provided at their lower ends with runners such as anti-friction rolls 21 to ride on guides 2:2 secured to the truck and inclined upwardly toward the rear of the truck, substantially horizontal seats or rests 23 and 24 being provided respectively at the forward and rear ends thereof to receive the runners respectively when the body is lowered and elevated.

Any suitable means for advancing the runners at the lower ends of the elements of the thrust member upon said elevated guides may be employed such as a drum 25 to which is secured one end of a cable or plurality of cables 26 extending around a roller 27 mounted axially with reference to the runners and terminally secured to the truck at 28. The revolution of the drum to secure the winding or unwinding of the cable or chain may be accomplished in any suitable manner as by gearing 29 actuated by power mechanism, either manual or motor.

In the construction illustrated the upper extremities of the elements of the thrust member are provided with guides 30 on the body and are connected with the elements of a rocker 31 consisting of links to the intermediate portions of which are pivoted the upper extremities of the elements of the f0rward supporting member 11, as shown at 32, the upper extremities of said rocker elements being pivoted as at 33 to the body while to the lower extremities thereof are connected the links 3% which extend to the upper ends of the elements of the thrust member. The result of this arrangement of parts, in operation, is that as the lower end of the thrust member is advanced upon the truck guide 22 the body is elevated upon the substantially fore and aft supporting members, but an increased upward movement is imparted to the front end of the body due to the action of the rocker operating through the links 34 to cause the upper ends of the thrust member to move forward in the body guides .30. The full line illustration in Fig. 2 shows the position of the body at a maximum elevation as when it is desired to deliver coal into a chute located. at a considerable distance from the point of discharge and enabling the operator to convey the coal from a wagon in the street or roadway to a comparatively distant point, such as the coal-hole of a dwelling or build ing located for example inside of the line of the pavement.

hen it is desired to deliver material from the body where a greater inclination of the latter is necessary, the locking means for the extension 16 may be removed to permit the elongation of the forward supporting member, as shown in dotted lines in Fig. 2, whereby a further upward movement of the fore part of the body is permitted. Thus the wagon or cart is adapted for the handling of various kinds of materials and for securing the prompt and satisfactory discharge thereof regardless of the angle of rest thereof, the adaptation of the vehicle to the peculiarities of the different materials being accomplished merely by securing or releasing the extension element which thereby is either permitted to act in conjunction wit or as an extension of the forward supporting member or is rendered inactive to permit the forward supporting member to operate independently thereof.

Having described the invention what is claimed is:

1. A dumping wagon having a truck or base and a body movably mounted thereon, pivotal supportin members forming fore and aft connections between the base and body, a thrustmember for elevating the body, an extension for the fore supporting member to vary the relative elevations of the ends of the body and consisting of an element movable relative to the member, and means for locking said element in its inoperative position.

2. A dumping wagon having a truck or base and a body movably mounted thereon, pivotal supporting members forming fore and aft connections between the base and body, a thrust member for applying elevating impulse to the body, an extension for the fore supportin member to vary the rela tive elevations of the ends of the body and consisting of apivotal shackle to which the said supporting member is pivotally connected, and means for locking the shackle in a fixed position with reference to the truck.

3. A dumping wagon having a truck or base and a body movably mounted thereon, pivotal supporting members forming fore and aft connections between the base and body, athrust member for applying elevating impulse to the body, an extension for the fore supporting member consisting of a shackle pivotally mounted upon the truck and having the lower extremities of the said fore supporting member pivotally connected therewith, and removable means for locking the shackles in fixed positions relative to the truck.

4. A dumping wagon having a truck or base and a: body movably mounted thereon, pivotal supporting members forming fore and aft connections between the base and body and arranged in approximate parallelism, a thrust member for applying elevating impulse to the body, guides being provided on the truck and body for the extremities of said thrust member, a connec tion between said thrust member and the upper extremity of the fore supporting member, a rocker to which the upper end of said supporting member is attached, and a releasable extension between the lower end of one of said supporting members and the truck.

This specification signed and witnessed this 27th day of November, A. D. 1917.
